The invention discloses a locomotive constant-speed control method and a locomotive control system based on a speed difference value, and relates to the technical field of locomotive speed control. The method comprises the following steps: S1, setting a target speed of a locomotive, and acquiring advancing speeds of adjacent vehicles in the same track by utilizing a communication network, the automatic constant speed control switch is started after the verification of the relative speed difference value and the safety distance is passed; s2, the actual speed of the locomotive in the current running process is obtained in real time, and the real-time speed difference value between the actual speed and the target speed is calculated to serve as the regulation and control difference value displayed in real time; s3, according to the numerical level of the regulation and control difference value, adopting a control strategy of multi-level regulation and control and step-by-step intervention; and S4, monitoring the regulation and control speed of the locomotive after regulation and control, and calculating an ideal difference value between the regulation and control speed and the target speed. The multi-stage control strategy is adopted, the speed of the locomotive can be flexibly adjusted under different conditions so as to adapt to the complex and changeable driving environment, and the stability and adaptability of the system are enhanced.

    本发明公开了一种基于速度差值的机车定速控制方法及机车控制系统,涉及机车速度控制技术领域,该方法包括:S1、设定机车的目标速度,利用通讯网络获取同轨道内邻车的行进速度,并在相对速度差值与安全距离验证通过后启动自动定速控制开关;S2、实时获取机车当前运行过程中的实际速度,并计算实际速度与目标速度之间的实时速度差值,作为实时展示的调控差值;S3、依据调控差值的数值等级,采用多级调控、逐级介入的控制策略;S4、监控机车在完成调控后的调控速度,计算与目标速度之间的理想差值。本发明采用多级调控策略,在不同情况下能够灵活调整机车的速度,以适应复杂多变的行车环境,增强了系统的稳定性和适应性。
